The size of children's feet is difficult to measure, so part of Froddo’s collection has ‘smile’ antibacterial insoles. The printed ‘smile’ on the insole shows the ideal place for the big or longest toe. The insole can be simply removed from the shoes and placed on the floor. When a child stands on the insole you can see straight away if the size is correct. The insoles are made of recycled antistatic materials and are highly absorbent preventing the development of bacteria and reducing sweat. Very light and stable they are anatomically shaped with an anti-shock effect.
